► ARE YOU READY TO SERVE AND PROTECT? It’s a desperate mission that only the brave and resourceful will survive: Your base is under attack and the enemy are pressing in on all sides. Only you and your tiny squad of special forces operatives can save the day, so parachute in and prepare to defend using everything you can get your hands on in this all-action tower defense game. Battle it out against wave after wave of invaders, secure the area, grab the loot and head for the next war-torn location in this fast-paced game that combines smart strategy with wild action. ► IT’S BASED! Army Defence combines the best elements of traditional tower defense games with intuitive gameplay and a host of original features: • Time spent in reconnaissance: Before the battle begins, you have a little time to build up your defenses, with a variety of artillery posts, sniper towers, mines and other objects to be placed and upgraded. Scout the terrain, spend your resources wisely, and keep an eye on the clock. • Pick your hill: In this gripping action game, it’s your tiny squad against a whole army of invaders, so deploy your troops carefully to minimize their exposure to incoming fire. And when the action begins, be sure to keep moving! • Ride the waves: Wait for the enemy to arrive or start the action yourself. Each battle is divided into waves, and each wave is going to be even tougher than the last. Fight off a whole army of paratroopers, snipers, and heavy infantry, with air support and a huge range of armored vehicles. Who knows what the next wave will bring? • Spoils of war: Between the waves, make sure to take a thorough look around the area – you’ll be surprised at all the goodies you can find, but unsurprisingly, you may have to fight for them. • Intensive training: When the battle’s over, head to the store and spend your hard-earned on loot on upgrades, equipment, and new recruits, ensuring your little army is armed to the teeth and more than ready for whatever the next mission throws at you. • Fight them on the beaches: Move from forest to desert to snow-capped mountains – in this epic tower defense game your next mission could take you anywhere. Just don’t get too distracted by the beautiful scenery when the bullets start flying. ► WHO DARES WINS Looking for a tower defense game that’s exciting, easy to play, and offers a huge range of varied challenges? Can you keep your head when all around are losing theirs in a hail of bullets and the fog of war? Only bold and decisive action can save the day, so download Army Defence now and get ready for some serious soldiering.

Verdict
The clearest difference is rating: Army Defence! at 4.6 against Z's 3.4. Army Defence! also leads on ratings volume (11K vs 319). Z's advantage is update cadence (fortnightly vs every 6 weeks) and review sentiment (35% vs 22%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Z sells 4 one-off in-app purchases and Army Defence! sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Army Defence! holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: Army Defence! has 11K ratings behind it against 319, so its average is the more settled of the two. Written reviews complicate that: 35% of Z's written reviews are positive against 22% of Army Defence!'s, so the app with the better star average is not the one people write more warmly about.
Z ships an update fortnightly, Army Defence! every 6 weeks. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
